How do antistatic additives work?
Antistatic agents are used to manage static charges during various stages of processing and to provide long-term static protection based on end-use applications. Static electricity can occur during an imbalance of positive and negative charges in an object. When enough electrical charges accumulate on the surface, a discharge occurs. The negative impacts of an electric…

Additives for UV Stabilization
Nearly every plastic is prone to degradation when exposed to UV light, such as from sunlight or fluorescent lighting. This degradation can occur during processing or once the product is in service, and the symptoms include brittleness, discoloration, and loss of physical properties such as impact strength, tensile strength, and color – all leading to…

How Flame Retardants Work in Plastics
Flame retardants are chemical compounds added to plastics in order to prevent, delay, or slow down combustion, reduce smoke formation, and/or prevent the material from melt collapse (anti dripping). These additives are common in numerous everyday products to avoid the ignition and burning of plastics. The most common flame retardants are halogenated compounds, which include…
